[Elecraft] K3- external keyer problems

Guys,
Out of the blue, the external keyer input to the K3 produces mushy dits
at higher speeds. It seems that each dit has a tail which reduces the
off time till the next. This happens in the TEST mode as well as with
RF output. It is most noticable above 25 wpm on S,H,5 characters. The
first dit sounds OK but it gets worse with following dits.
I've tried two different keyers and now the parallel port keying is
exhibiting the same. I don' think it is a keyer issue since hooking the
keyers up to an audio oscillator sounds just fine.
I'm using firmware V2.76. I dropped back to 2.67, where I never had
observed this, and the problem is still there.
The internal keyer does not have this problem. If anything the dits
seem to get shorter as one goes above 30 wpm. That I'm sure is just a
perception. High speed CW ops often add additional weighting to make it
sound better.
Any suggestions?
